Application filed September posed outwardly at the apex, and an elementflexiblyatta'ched usually at the apex, so that it may be set in anupwardly. inclined position. In this manner I providea portfolio whichmay be employed as a triangular stand, and, in addition, the elementabove referred to acts as a support against which upturned leaves mayrest so that they are visible from'the same side of the portfolio as thedownturned leaves which rest against one of the cover members.

:Another object of the invention is to provide a portfolio having anextension on one of its cover members which will form the third sideofthe triangle, or? fold inwards over the leaves when the portfolio isclosed; the element and its support are also so constructed that theywill lie substantially flat against one of the cover members when theportfolio is in closed position. i

. Having thus briefly outlined the major purposes of the invention Iwill now proceed to describe an embodiment thereof with the aid of theaccompanying drawings in which the various views are drawn to differentscales.

Figure 1 illustrates the portfolio with one of the cover members partlyopen.

Figure 2 shows the portfolio with one cover member more fully open.

Figure 3 is a view of the portfolio in use as a stand, and

Figure 1 shows a modified form of support for the element.

In the drawings, 1 designates the front cover and 2 the back cover, bothof which parts are made of strong rigid material. The flexible portion 3which connects the inner ends of the cover members, has a loose leafbinder 4 attached to it, and the element 5 is also flexibly secured tothe portion 3 in proximity to one side of the loose leaf binder.Integral with the outer end of the back cover is a flexible portion 6 ofsufficient Serial No. 57,538.

length to fold over the outer edges of the leaves 7. At the outer end ofthe flexible portion 6 is an extension piece 8 which is in turn securedto the outer strip 9 by the jointlO.

The inner surface of the front. cover is .provided with fasteners 11which are adapted to cooperate eitherwith the fasteners 12 on the outersurface of the extension piece 8, or with the fasteners 13 on the outerstrip 9. v i

On the inner surface of the back cover bracketsl l are provided for thesupporting member 15 which is pivotally mounted therein, and is adaptedeither to engage clips 16and 17 on the back of the element 5 so that thelatter may be held in an "upwardly inclined position, or to liesubstantally flat against the inner, surface of the back cover? In Figure 3 aspring clip 17 is shown in addition to the ordinary type of In Figure 4a modified form of construc tion is shown; a' tab 14 is secured to theinner surface of the back cover and has a flexibly connected extension15 which may either be folded back against the inner surface of thecover asshown at 15 or brought into engagement with a lockingniember 17secured to the reverse side of the element 5. This form of constructionlsometimes employ for small portfolios in which the weight of the leavesis not sufficient to tend to bend the unsupported sides of the element.

When the portfolio is in closed position the flexible portion 6 isfolded round the outer edges of the leaves 7 and the extension piece 8and strip 9 lie flat between the inside of the top cover and the leaves.The element 5 is folded back against the inside of the back cover, andthe supporting memwith the fasteners 13 on the outer strip 9, which haspreviously been turned upwards about the joint 10. The element 5 is thenraised and held in position by the supporting member 15 which engagesthe clips 16 and 17. Or, in the design shown in Figure 4, the extension15 of the tab ll is brought into engagement with the locking member17 Inthis manner a stand is provided with the use of which two leaves, oneupturned and the other downturned, are visible from one and the sameside of the portfolio, whereas without the use of the element 5 thiswould not be the case; and again the arrangement is such that both sidesof each leaf may be displayed in turn.

In the foregoing mention has been made of a loose leaf binder thoughobviously bound leaves may also be arranged in the portfolio. And whilethe preferred form of construction of the invention has been describedand shown, it is understood that any modifications may be made thereinthat fall within the scope of the appended claims.

' What I claim as my invention and desire to secure by Letters Patentis 1. A portfolio comprising two cover members connected at their innerends and adapted to open so that their outer surfaces are towards oneanother thereby forming two sides of a triangle, an element flexiblymounted in proximity to the inner end of one of the cover members andadapted to assume an upwardly inclined position, means for holding saidelement in saidupwar'dly inclined position, and means for holding theouter ends of the cover members in spaced relation to one another.

2. A portfolio comprising two cover members connected at their innerends'and adapted to open. so that their outer surfaces are towards oneanother thereby forming two sides of a triangle, an element flexiblysecured to the connecting portion between said cover members, and anextension piece integral with one of said cover members adapted to formthe base of the triangle, in combination with means adapted to supportsaid element in an upwardly inclined posiprovided for the element topositively engage the supporting means.

5. In a portfolio, the combination of two cover members, a connectingportion between the inner ends of said cover members, a loose leafbinder on said connecting portion, an

element flexibly secured to said connecting portion, and a supportingmember for said clement pivotally mounted on one of said cover members,said element and said supporting member being adapted to lie substantially flat one on the other against the inner surface of the covermember to which said supporting member isisecured when the portfolio isin closed position.

6. A portfolio comprising two cover members connected at their innerends and adaptcd'to open so that their outer surfaces are towards oneanother thereby forming two sides of. a triangle, an element flexiblymounted in proximity to'the inner end of one of the cover members, anextension piece integral with one of the cover members adapted to formthe base of the triangle, and a pivotally mounted support on one of thecover members adapted to hold said element in upwardly inclinedposition.
